Start cutting on that Dodge. You can use both cross members and trans. and tcase if equipped. A getrag 5 speed centers right up in the trans. tunnel hole. Fan space is tight but a thin electric will work. I am in the middle of installing an aftermarket innercooler where all I had to do is drill two, three inch holes in the upper core support. Its a little noisy but I get between 15-16 mpg and when the tops off who cares!
